“…Previous studies have reported a high proportion of moth singletons in forest habitats (WILLOT 1999, RICKETTS et al 2001, BREHM et al 2003, HILT & FIEDLER 2005. We suggest that the relatively low density of individuals in the grassland is the most probable factor accounting for the observation of a higher proportion of singletons in this habitat.…”

The Atlantic Forest is considered a biodiversity hotspot for conservation, because its fauna and flora are highly endemic and suffer from loss of natural habitats. This study assessed the composition and diversity of tiger moths (Lepidoptera: Arctiidae) in two floristic formations of the southern Atlantic Forest (grassland and Araucaria forest) and in a transition zone (forest edge). The moths were attracted to UV light reflected onto a white sheet. A total of 3,574 tiger moths were collected, representing 121 species. The rarefaction curves showed that the tiger-moth assemblage collected in the grassland was more diverse than the assemblages from the Araucaria forest and the transition zone. The assemblages in the forest and forest edge resembled each other, whereas the grassland assemblage was distinct. The composition of the tiger-moth assemblages was related to the environmental characteristics [habitat type (grassland, edge, or forest), altitude, temperature, air relative humidity] and the location of the sites. The faunal similarity decreased in response to increasing environmental and geographical distances between the sites. The responsiveness of tiger moths to small-scale variation in environmental and geographical parameters indicates their good potential as environmental indicators

“…For example, in the Amazon litter beetles need more than 1 km 2 of intact forest to subsist (Didham 1997). The above considerations may apply only to insect herbivores in the understorey (for canopy insects see Willott 1999). In sum, we found some support for RIL from a conservation viewpoint and, above all, for promoting studies that examine how best RIL could minimize the loss of biodiversity in tropical wet forests.…”

Summary 1.A before/after-control/impact experiment (BACI) was used to examine the shortterm effects of canopy openness on insect herbivores foraging on the seedlings of five rain forest species in an unlogged forest in Guyana. During the first and second study years, insects were collected monthly from 250 sites, representing 9750 seedlings spread over a plot of 1 km 2 . At the onset of the second collecting year, half of the parent trees at the sites were felled, creating an average canopy openness of 26%. 2. Comparisons of the control and impact sites before and after the felling showed that overall insect abundance, particularly of psyllids, and species richness increased at the impact sites, whereas evenness decreased markedly. These responses were consistent with the prediction that intermediate disturbance promotes high diversity in tropical systems. 3. Twenty-nine per cent of insect species analysed showed a significant response to felling, with some populations doubling or halving at the impact sites after felling. The abundance of most species increased, although responses varied even between congeners. 4. A canonical correspondence analysis at the impact sites after felling indicated that most species responded to an increase in leaf production by seedlings, not to canopy openness per se . Species declining at the impact sites were more likely to feed indiscriminately on young and mature foliage and probably reacted to changes in microclimate. 5. The study illustrates the difficulty in identifying higher taxa, umbrella or indicator species that adequately integrate the responses of insect herbivores to forest disturbance. Because the integrity of insect communities in the understorey of this forest depends more on minimizing damage to plant resources than on canopy openness, we found some support for the conservation value of reduced impact logging in tropical wet forests.

“…Forest degradation is broadly defined as the long-term reduction of the overall potential supply of goods and services, including carbon storage, wood production, and biodiversity conservation. The impacts of individual forms of tropical forest degradation are understood in outline; for example, industrial logging reduces carbon stocks (3)(4)(5) and changes biodiversity, often reducing it (5)(6)(7)(8). Deforestation and degradation patterns have been related to road access, road density, topography, and biophysical characteristics such as soil fertility (9)(10)(11)(12)).…”

Tropical forest degradation emits carbon at a rate of~0.5 Pg·y −1 , reduces biodiversity, and facilitates forest clearance. Understanding degradation drivers and patterns is therefore crucial to managing forests to mitigate climate change and reduce biodiversity loss. Putative patterns of degradation affecting forest stocks, carbon, and biodiversity have variously been described previously, but these have not been quantitatively assessed together or tested systematically. Economic theory predicts a systematic allocation of land to its highest use value in response to distance from centers of demand. We tested this theory to see if forest exploitation would expand through time and space as concentric waves, with each wave targeting lower value products. We used forest data along a transect from 10 to 220 km from Dar es Salaam (DES), Tanzania, collected at two points in time (1991 and 2005). Our predictions were confirmed: high-value logging expanded 9 km·y −1 , and an inner wave of lower value charcoal production 2 km·y ; 0.1 species per sample area (0.4 ha)]. Our study suggests that tropical forest degradation can be modeled and predicted, with its attendant loss of some public goods. In sub-Saharan Africa, an area experiencing the highest rate of urban migration worldwide, coupled with a high dependence on forestbased resources, predicting the spatiotemporal patterns of degradation can inform policies designed to extract resources without unsustainably reducing carbon storage and biodiversity. biodiversity conservation | carbon emissions | reducing emissions from deforestation and forest degradation | sustainability | tropical forest degradation
